Gas Safety Certificate Lambeth — from £64.99

What is a Gas Safety Certificate (CP12)?

A Gas Safety Certificate, formally known as a CP12, is a document confirming that all gas appliances, flues and pipework in a rental property have been inspected by a Gas Safe Registered engineer and found to be safe. The engineer checks each appliance for correct operation, adequate ventilation, secure flue connections and correct gas pressure, and lists every appliance on the certificate along with its result.

Every private landlord in England has been legally required to hold a valid CP12 and renew it every 12 months since the Gas Safety (Installation and Use) Regulations 1998 came into force. Landlords in Lambeth are subject to exactly the same obligation as landlords elsewhere in England.

Gas safety in Lambeth — local property context

Lambeth is one of London's most active rental boroughs, with large stocks of Victorian terraces in Brixton, Stockwell, and Clapham, converted mansion blocks in Streatham, and significant estate housing throughout. HMO activity is very high across the borough. Many Victorian conversions have ageing electrical systems, and EICR inspections frequently identify missing RCD protection.

One of the highest rental yields in inner South London. Very high tenant demand driven by Northern line and Victoria line access. Our Gas Safe registered engineers are experienced with the boilers, gas fires and appliances typically found in properties across the SE1, SE5, SE11, SE24, SE27, SW2, SW4, SW8, SW9, SW16 postcode areas, and regularly carry out CP12 inspections across Lambeth for private landlords, letting agents and HMO operators.
